The spin-polarized chromium (Cr) tip being scanned over the pristine superconducting area of the C2 magnetic order, represented in the background with electron pairs shown as coupled red spheres. The spin current through the tip induces the C4 magnetic order (yellow and blue plaquettes) with suppressed superconductivity in the sample because its spin fluctuations cannot mediate electron pairing, represented as decoupled red spheres in the plaquette area.
Materials that can maintain a magnetized state by themselves without an external magnetic field (i.e., permanent magnets) are called ferromagnets. Ferroelectrics can be thought of as the electric counterpart to ferromagnets, as they maintain a polarized state without an external electric field. It is well-known that ferromagnets lose their magnetic properties when reduced to nano sizes below a certain threshold. What happens when ferroelectrics are similarly made extremely small in all direction
2024-05-31< (From left) KAIST President Kwang-Hyung Lee and Merck CEO Matthias Heinzel > KAIST (President Kwang-Hyung Lee) signed a Memorandum of Understanding (MOU) with Merck Life Science (CEO Matthias Heinzel) on May 29 to foster innovation and technology creation in advanced biotechnology. Since May of last year, the two institutions have been discussing multidimensional innovation programs and will now focus on industry-academia cooperation to tackle bioindustry challenges with this MOU a
2024-05-30What if there is a biodegradable packaging material with high performance without leaving microplastics? Plastic pollution presents a global challenge that must be solved. In particular, packaging accounts for 30-50% of the total plastic consumption. While paper packaging is eco-friendly, it lacks crucial functionalities like moisture resistance and strength. Traditional coating materials exacerbate plastic pollution, prompting the need for sustainable alternatives. Polyethylene (PE) and e
2024-05-22Unlocking biological information from complex single-cell genomic data has just become easier and more precise, thanks to the innovative 'scLENS' tool developed by the Biomedical Mathematics Group within the IBS Center for Mathematical and Computational Sciences led by Chief Investigator Jae Kyoung Kim, who is also a professor at KAIST. This new finding represents a significant leap forward in the field of single-cell transcriptomics. Single-cell genomic analysis is an advanced technique that m
2024-05-09Sodium (Na), which is over 500 times more abundant than lithium (Li), has recently garnered significant attention for its potential in sodium-ion battery technologies. However, existing sodium-ion batteries face fundamental limitations, including lower power output, constrained storage properties, and longer charging times, necessitating the development of next-generation energy storage materials. On the 11th of April, KAIST (represented by President Kwang Hyung Lee) announced that a research t
